GOMBING MACHINE.

Application filed March 21, 1923.

To all whom it may concern:

Be it known that I, JOHN IVILLIAM NA- SMITH, of Heaton-hilersey, Manchester, England, a subject of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Combing Machines, of which the following is a specification.

In the Nasmith combing machine it is usual to weight the front leather covered detaching roller on each end by a simple hook passing down below the rollers, its lower end being formed to receive the usual weight. When it is necessary to remove the roller the hook, provided with a finger hole for the purpose, is easily lifted from the neck of the roller and placed on the ad jacent support (T, Fig. 1). The hook and weight hang loose in this position and are frequently knocked off and fall to the floor causing unnecessary stoppage of the machine until they are recovered.

Although the hooks are easily removed it takes an appreciable time to place them properly and securely on the support.

The object of the present invention is to do away with all loose parts that may get out of position or fall and to make the removal and replacement of the hook practically instantaneous, thus appreciably diminishing the time the eomber must stop when a roller must be removed from any cause.

The invention will now be fully described with reference to the accompanying drawings, which are not to any special scale, and wherein Figure 1 is a vertical section through part of a Nasmit-h combing machine, suflicient of the machine being shown for purposes of description of the invention. The parts are shown in this figure as in position for applying the pressure to the roller. Figure 2 is a similar section to Figure l the pressure being removed; and Figure 3 is plan of the parts constituting the invention.

Referring; to 1 of the appended drawings, which is a section through part of a l asmith combing machine, D is the front leather covered detaching roller to which pressure is to be applied at both ends, H is an L-shaped lever or weight hook which transmits the pressure of the spring N to the neck of the roller. one at each end. The bracket B, shown in plan in Fig. 3, is fixed on the top of the hearing of the bottom rollers and is formed Serial No. 626,659.

with a fork F to receive the end of the top roller D and a boss to carry the pivot P on which the weight-hook is engaged. The hook H is formed with a slot S, having a depression at E (Fig. 2) at one end. A piece C, adjustable along the framing of the machine 13, serves to regulate the tension of the spring N. In Fig. 1 the parts are shown in working position with the pressure on the roller. The pull of the spring N keeps the depression E engaged on the pivot P, which acts as a fulcrum and pressure is tansmitted to the rollers. A slight press with the finger in the direction of the arrow A (Fig. 1) suflices to disengage the depression from the pivot at the same time slightly increasing the tension of the spring and a soon the de pression is clear of the pivot the slot S permits the springN to instantly pull the whole weight hook to the left and transfer the forward end of the hook from the neck of the roller to the support T where it rests securely, there being no loose parts to get displaced or fall, the whole being in stable position as shown in Fig. 2. To replace the n'essure on the neck of the roller a push in the direction of the arrow A (Fig. 2) suflices and the spring instantly locks the hook in position.

The apparatus is described and shown applied to the rollers of a Nasmith combing machine, but it may be applied to other machines.

I claim 1. Apparatus for applying pressure to the top rollers of textile machines, said apparatus comprising a lever operating in a fulcrum pin on the machine framing and bodily movable in relation to said fulcrum pin, and tensioning means applied to one extremity of the lever to apply pressure at the other extremity thereof around the fulcrum to the roller, the lever being so arranged that manual pressure applied thereto will move it about its fulcrum and in that position allow the tensioning means to pull the lever bodily away from the roller being weighted, the whole lever moving bodily in relation to its fulcrum pin.

2. In apparatus for applying pressure to the top rollers of textile machines. a lever operating about a fulcrum pin. one extremity of the said lever resting on the neck of a roller to be weighted and the other having tension applied to it, a rest for the pressure end of the lever and an L-shzrperl the pressure end of the lever, and on the slot in the lever in one branch of which the other lland'to pull the other branch of the 10 fulcrum pin engages; so that movement.
